一道SAT语法
The ancient manuscript was a valuable find,even though the writing was difficult to decipher and the paper 【had begun】 to disintegrate.
the answer is that "had begun"has no error,but i think maybe something wrong with tense of it ...could you explain ...
When the ancient manusicript was discovered,the paper had begun to disntedrate.
"begun" happened before it was found.I think the past perfect tense is right.
